Embodiment Construction

[0030]The intra-aortic dual balloon pump catheter device of the present invention will be described in detailed embodiments with reference to the accompanying drawings. It shall be noted that the accompanying drawings are given by way of illustration only, and shall not be construed as limiting the present invention.

[0031]The intra-aortic dual balloon pump catheter device is guided by a guide wire 1 of a catheter 2 and reaches a predetermined position within the aorta, and then the guide wire 1 exits from the catheter 2.

[0032]FIG. 2 shows a partial section view of an intra-aortic dual balloon pump catheter device according to the first embodiment of the present invention. As shown in the figure, a first balloon 4 and a second balloon 6 are arranged to successively surrounding the catheter 2 along the longitudinal direction of the catheter 2, wherein the position of the first balloon 4 is closer to a catheter end 5 than the position of the second balloon 6. A first intake pipe 3 and ...

Abstract

The present invention relates to an intra-aortic dual balloon pump catheter device. The intra-aortic dual balloon pump comprises: a catheter (2); a first balloon (4) and a second balloon (6) arranged to successively surrounding the catheter along the longitudinal direction of the catheter (2), wherein the position of the first balloon (4) is closer to a catheter end (5) of the catheter (2) than the position of the second balloon (6); the first balloon (4) and the second balloon (6) are periodically expanded to a dimension that blocks the aortic blood flow and contracted to a dimension that does not prevent the blood flow from passing through; wherein the first balloon (4) begins and finishes the inflation earlier than the second balloon (6) in each period of expansion and contraction.

Description

TECHNICAL FIELD[0001]The present invention relates to an intra-aortic dual balloon pump catheter device.BACKGROUND ART[0002]Intra-aortic balloon pump (IABP) is a mechanically assistive circulatory device widely and effectively used in the current clinical application. It is a cardiac catheterization therapy wherein a catheter with a balloon is implanted through the arterial system to an end proximal to the heart within the descending thoracic aorta , or an end distal to the left subclavian artery opening, inflating and deflating correspondingly to the cardiac cycle such that the blood changes in time phase within the aorta so as to mechanically assist the circulation. The aim is thus achieved to reduce aortic impendence and to increase aortic diastolic pressure while reducing myocardial oxygen consumption and increasing oxygen supply, so as to improve the function of the heart.[0003]The intra-aortic balloon pump (IABP) may be applied to different situations to improve the patients h...
